As an elementary art teacher, I spend a pretty fair amount of time hanging artwork in the hallways. It is pretty time consuming, but is worth it. One day after school, I was hanging a project. I have what I considered to be a pretty good stapler. It was a Swingline after all. Even with a nice quality stapler, it would jam relatively often. As I was fumbling with trying to get a jammed and bent staple out of the stapler, a teacher walked by and mentioned that a colleague had a new kind of stapler that was stronger and didn't jam.
After doing a bit of research, I found that it was a Paper Pro stapler. I immediately ordered one and have loved having it. It staples easily into cork boards as well as directly into walls. It also doesn't jam! The mechanism is designed differently than ordinary staplers and almost feels like a staple gun. I thought I'd share with everyone. Here is a link to the stapler on Amazon --> http://www.amazon.com/Paper-Pro-1110-PaperPro-Prodigy/dp/B000GGY9LY/ref=pd_sbs_op_1
